The oxidation number of calcium (Ca) in CaF2 is +2. This is because fluorine (F) typically has an oxidation number of -1, and the overall charge of CaF2 is neutral. Since there are two fluorine atoms each with a -1 charge, the calcium atom must have a +2 oxidation number to balance the charges.
The oxidation number of calcium in calcium fluoride (CaF2) is +2, because calcium typically forms ions with a charge of +2. The oxidation number of fluorine in CaF2 is -1, because fluorine usually has a charge of -1.
The oxidation number of Calcium (Ca) is +2
Fluorine's oxidation number is -1. Since there are four fluorine atoms, the total oxidation number for the fluorine portion of the molecule is -4. The carbon atomwould have to have an oxidation number of +4 so that the compound would have an overall oxidation number of 0.
The oxidation number of calcium (Ca) is +2 and the oxidation number of phosphorus (P) is -3. Therefore, in Ca₃P₂, the oxidation number of calcium is +2 and the oxidation number of phosphorus is -3.
There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.

CaF2, Calcium Fluoride. It is useful in iron smelting
Calcium fluoride, CaF2
The reason it becomes stable is because Ca has 2 valence electrons that it wants to get rid of to become stable. F has 7 valence electrons and wants 1 more to become stable. So, TWO F atoms each take 1 of the 2 electrons from Ca. They form an ionic bond as Ca^2+ and 2F^- to make CaF2.
The oxidation number of calcium in bleaching powder (calcium hypochlorite) is +1. In the compound Ca(ClO)2, the total oxidation numbers of chlorine (-1) and oxygen (-2) balance out to zero, so calcium must have an oxidation number of +1 to maintain overall charge neutrality.
There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.
The only oxidation number is 2+.
The oxidation number of calcium in the compound CaOCl2 is +2. In compounds, the sum of the oxidation numbers must equal zero, and since oxygen has an oxidation number of -2 and chlorine has an oxidation number of -1, the calcium ion must have an oxidation number of +2 to balance the charges.
Ca+2 F-1 <----- these are the ions and their charges Ca+2 F-1 F-1 <----- the charges have to add up to zero, so two -1 fluorine ions cancel out one +2 calcium ions CaF2 <---- simplify
